1H NMR spectra of Boc-APNBMA monomer (top) in CDC13, mPEG-b-P(Boc-APNBMA)n (middle) in CDC13, and mPEG-b-P(APNBMA•HCl)n (bottom) in DMSO-d6. Letters with a single prime (′) indicate resonances from the protected BCP and letters with a double prime (″) indicate resonances from mPEG-b-P(APNBMA•HCl)n.
